NR - Non-return Check Valve

The NR - Non-return Check Valve provides an effective solution for preventing reverse flow from the tank back into the supply line. The valve remains open when the inlet pressure is higher than the outlet pressure, and closes automatically to stop reverse flow when the flow direction is inverted, ensuring reliable system protection.
